CONTROL APPARATUS FOR THE POSITION OF SIGNAL-DISKS.

SPECIFICATION forming part of Letters Patent No. 461,657, dated October20, 1891. Application filed November 29, 1889. Serial No. 332,005. (Nomodel.)

2" 0 all whom it may concern:

Be it known that I, THEODOR WEIssER, of Viihrenbaclninthe Grand Duchy ofBaden and German Empire, have invented a new and useful ControlApparatus for the Position of Signal-Disks, of which the following is aspecification, reference being had to the accompanying drawings.

The controlling apparatus of the nature hereinafter described has forits object to verify at a distance the momentary position or placing ofa certain devicefor instance, a.

switch, a toll-gate, a railway-gate, &c.and to indicate the period andlength of time the said device has been in one or the other position.The signals are shown on a table provid ed With colored disks orlanterns, and they are simultaneously registered on a strip of paperdivided into the different parts of time and driven by a clock-work. Themarks upon the registering-strip are effected by a pencil,

arrow. Fig. at is a section on line y ofFig. 3. Fig. 5 is a horizontalsection through the controlling apparatus on line .2 z of Fig. 1; andFig. 6 shows, diagrammatically, the device of a switch and of arailway-gate provided with the present invention.

The controlling apparatus is so arranged that by changing the positionof a device which is connected with itan electric current is closed oropened. The current in passing through an electro-magnet attracts itsarmature, which produces a double effect: First, a disk is broughtbefore the opening of the table, and, second, a pencil connected to thearmature by means of a lever is pressed against a paper strip constantlydrawn along by means of a clock-work, so that a line is formed on thepaper. As this paper strip moves a certain distance in a certain lengthof time, it follows that the exact hour can be determined when themotion of the device (such as the switch) has been effected and how longthe same has been in the changed position.

The drawings show a device with three magnets used during the operationof a switch and of a railway-gate I will first describe the inventionwith respect to the signal placing.

M, Fig. 1, is an electro-magnetto be energized by an electric current,as will be hereinafter specified. When the electro-inagnct is energized,it attracts an armature a, causing the latter to turn on its pivot aagainst the force of a spring or, hooked to frame T and holding thearmature in its normal position. The front end of the armature a isconnected by the rod 1) with a lever I), turning at b and carrying atits end a signal-disk c. The said disk is placed before the opening (Zof the table as soon as the armature a is attracted, and thus a coloredsignal is lifted in sight.

In order to register the changed position of the signal, I make use ofthe following device: The back end a of the armature a is connected by arod 6 with a lever g, keyed on a shaft f. This shaft f enters the caseof the registering apparatus and carries at its back end a link '11,pressing against a lever 7.1, turning on the shaft 7;, while the frontend of the lever Z: is provided with a pencil j just above a roller Z,as shown in Figs. 2, 4, and 5. The armature a being attracted, shaft fis so turned that the link i is lowered to cause the pencil j to restupon the roller. \Vhen, on the contrary, the electro-magnet M is notenergized and its armature a is not attracted, the lever it, under theaction of a spring a, will be drawn away from the roller Z. Aregisteringstrip 1) is led over roller Z, coming from the paper-roll o,and passes over the cylinders 20, Z, and w and between pressing-rollers0' r, which pull it along in a slow regular motion, regulated by anescapement device having the following construction: The cog-wheels onthe rollers r "1", gearing together, are also in gear with the wheel as,keyed on the shaft of a worm-wheel 50', which drives the worm 1 theshaft of which carries the fly .2, provided with two notches L and L Theend L of a lever u, having its fulcrum at u and receiving an oscillatorymotion, is made to pass alternately through the said notches L and L Aclock-Work B, indicating the time in the usual manner, imparts motion toa ratchet-Wheel 5, operating the 'end if of a knee-lever t 25, havingits fulcrum on the frame at 25 the arm t of lever 25 6 being connectedwith the lever 10 by means of the rod 25 By the revolution of Wheel .9in the direction of the arrow shown in Fig. 2 the arm 25' will bealternately raised and lowered, thereby raising and lowering the end Lof the lever to. \Vhen this lever is in the position shown in Fig. 2,the fly .2 can pass and will make half a revolution till its oppositeedge abuts against the end L of the lever 11.. Hereupon the end L oflever to, actuated by the kneelever 25 It, will be lowered till itpasses into the notch L and the fly can again make a furtherhalf-revolution. The progress of the wheel 8 for one tooth effects,therefore, halt a revolution of the fly, and the rollers '1 v" arepulling out a certain part of the registeringstrip.

It is obvious that while the electro-magnet M is energized the penciljwill produce a line on the registering-strip. cal figure shows suchlines, and indicates, also, how the apparatus is arranged for a doubleswitch and for a railway-gate.

1 is a track, 2 the neighboring track, 3 one switch, and 4 the otherswitch. The shifterblade 5 of the switch 3 is connected at 6 with thewire 7 8, leading to a battery D, which is connected by a wire 9 withthe electromagnets M M M over which the current passes to the conductors10 11 12, through 10 to the rail 13 of the main track, and through 11 tothe gate 0, the post C of which is connected with the Wire 8 by the wire14. The conductor 12 is electrically connected at 23 to theshifter-blade 16.

The electro-magnets and the registering apparatus are everywhere of thesame con- The diagrammati-- struction, and the above-explained device ofcontrolling apparatus is the same for a switch as well as for arailway-gate.

Suppose that the switch 5 be so displaced that the main track 1 isconnected with the adjacent track 2. An electrical contact will beeffected between 18 and 5, and the current passes from the battery Dthrough the 0011- ductors S, 7, 6, 5, 13, and 10 to the electromagnet Mand through the wire 9 back to the battery. The electro-magnet isenergized, the disk 0 is placed in sight, and the pencilj is allowed todrop down upon the strip of paper. It now the switch 4: is shifted inthe secondary track, so as to form a connection between 2 and 16, thecurrent will pass from the battery through 8, 15, 2, 1(3, 13, and 12,electromagnet M and wire 9 back to the battery. The electro-magnet Mthen brings the signal-disk c in sight, and the pencil marks the strip.Finally, when the gate Ois closed, electric contact is establishedbetween C and O, and the current passes from the battery D over 8, 14,O, O, 11, and electro-magnet M back to the battery. The disk 0 will beshown on the table, and the pencilj is made to register.

Having thus described my invention, what I claim is A controllingapparatus for railway signals, switches, and the like, consisting of aclock-Work B, rotating the rollers r and 0', which transport the paperstrip 19, in combination with the register-lever k, which is acted uponby the electro-magnet M and its armature a, which latter workssimultaneously certain signal panes 0r plates 0 c on the show-table T,substantially as described.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.

THEODOR XVEISSER.
